INTRODUCTION
ATTENTION INSTALLER: To assure a trouble free installation,
please read these entire instructions through once before
beginning.
The Sigtronics UltraSound Tactical Intercom System, when used with
Sigtronics noise attenuating headsets provides the tactical transport
crew with clear, hands free, voice activated (VOX) intercom. The
system also allows full radio monitoring at all headset positions as
well as radio transmit capability from selected headsets via Push-
To-Talk (PTT) switches.
Applications: The unit is designed for tactical, rescue and mobile
command center vehicles.
Voice Activated Intercom (VOX) feature allows “hands free” com-
munication between headsets connected to the UltraSound unit.
Start speaking and the intercom turns on instantly to relay your
message clearly to the other headsets. Stop talking and it turns off
to reduce background noise.
Up to Twelve Headset Positions can be connected to the Ultra-
Sound unit models UT-12S and UT-12D. More headset positions can
be achieved by wiring additional jacks in parallel. Only one headset,
however, can be plugged into paralleled jacks at one time. In the
case of the Driver, he plugs his headset into his jack while driving.
He then unplugs and plugs into the Driver’s Auxiliary jack when he
arrives on scene.
